Paramount, which acquired rights to the unique project earlier this year, announced the date on Monday.

Worlds Away features performances from elaborate Cirque du Soleil productions and an original story from Adamson, who is producing the movie with Aron Warner and Cirque du Soleil's Martin Bolduc, Ed Jones and Cary Granat.

Vince Pace, co-chairman of 3D technology and production services firm Cameron Pace Group, oversaw the 3D stereo production aspect of the movie.

Worlds Away will have plenty of competition. Also opening on Dec. 21 are Ang Lee's Life of Pi, Kathryn Bigelow's untitled Navy SEALs film, an untitled Judd Apatow comedy and Brad Pitt starrer World War Z.

Paramount made two other tweaks to its slate. The studio is changing the name of the previously titled Seth Rogen-Barbra Streisand comedy My Mother's Curse to The Guilt Trip. The film's release date of Nov. 2 remains the same.

The studio also is moving the release of Josh Schwartz'sFun Size from Oct. 12 to Oct. 26. The pic stars Victoria Justice, Johnny Knoxville and Chelsea Handler.
